It uses interconnect path tag to indicate the bandwidth voting is for which buckets, and there have three kinds of buckets: AWC, WAKE and SLEEP, finally the wake and sleep bucket values are used to set the corresponding clock (active and sleep clocks). So far, we keep the AWC bucket but doesn't really use it.

Move the function to a new common file icc-common.c so that allow it to be called by multiple drivers.

We're exluding ALC, IP0 and all _display nodes. ALC will not be voted from the kernel[1] and IP0 is handled by the clk-rpmh driver[2].

The topology consists of 3 NoCs: BIMC, Config NoC (CNOC) and System NoC (SNOC). SNOC is a QCOM_ICC_QNOC type device, as well as its 3 virtual child devices, QUP, MMNRT and MMRT. QUP is owned by RPM and thus has no .regmap_cfg, while the other 2 share the same .regmap_cfg with SNOC (parent).
